Sensory bins are a simple, yet highly effective addition to any primary classroom! Students can explore, create, and learn while engaging in sensory play. This DIY spring themed sensory bin incorporates one of the most important math skills for your primary learners. Subitizing is the ability for students to recognize or identify a number or the number of objects in a set without counting. It is the springboard for building a strong number sense and it is the key to establishing mental math reflexes!

In order to get started dying the rice for your bin, you’ll need these materials:
-3 cups of rice
-3 tsp. vinegar
-Food coloring or gel (amount varies based on desired color)
-Gallon Zip-lock bag
-Paper plate

Combine all ingredients in a gallon sized zip-lock bag, cover and shake well until rice is covered. Add green as needed. If you’re looking to make it more of a lime green, add some yellow food coloring. Leave on a paper plate to dry for an hour.

My favorite aspect of making a sensory bin is having the autonomy to create and utilize sensory objects that best fit the needs of my learners. In this case, incorporating fine motor skill practice was also a goal of mine. With this being said, I chose to add plastic Easter eggs and mini counting erasers to my bin. Students can gain extra fine motor practice by opening and closing the Easter eggs, as well as finding, picking up and counting out the spring themed erasers.

I’ll introduce the sensory bin as a “Spring Subitizing Egg Hunt” center and use it all month long in my math workshop rotations. Students will explore the sensory materials in the bin to find and sort the different representations of each number (1-10). The different representations include the number words, tens frames, dice, dominos, pictures and tally counts. You can find a sample of “Easter egg hunting” for the number “one” in the image above.

I plan to also use the same sensory bin materials, but incorporate other learning goals, such as addition/subtraction facts, sight words, etc. For example, the Easter eggs can hold different types of math facts. Students can then practice their fact fluency by sorting the facts by strategy. This practice supports their flexible thinking and enhances their number sense!

I hope this post has inspired you to create a spring sensory bin for your classroom and ignited you to modify it to fit the needs of your learners.
